Description
This HP EM153AV memory kit provides a substantial 4GB of RAM, divided into two 2GB FB-DIMM modules, operating at a DDR2-667MHz frequency. FB-DIMMs are a specialized memory technology designed for servers and high-end workstations, incorporating an Advanced Memory Buffer (AMB) chip. This chip serializes data transfers, significantly reducing the electrical load on the memory controller and enabling higher memory capacities and speeds, which is essential for demanding enterprise applications. The 2Rx4 configuration signifies that each 2GB module is dual-ranked, with each rank having a 4-bit data width. This configuration can offer performance advantages in specific memory access scenarios. The CAS Latency (CL) of 5 indicates the number of clock cycles delay between issuing a read command and the data being available, providing a good balance for server workloads requiring both speed and stability. As ECC Registered memory, these modules include Error-Correcting Code (ECC) to detect and correct memory errors, ensuring data integrity and system reliability. The registered nature of the modules further reduces the electrical load on the memory controller, supporting larger memory configurations. The EM153AV is specifically designed for HP server platforms that require DDR2 FB-DIMM memory, guaranteeing compatibility and optimal performance for critical business operations.
